This isnt rocket science. Year after year, young men, young local men, in what is one of the most underpopulated countries in the world, do jail time for smoking a spliff.
As I type this, doctors, lawyers, teachers, and a large amount of CEO's and entrepeneurs, are lighting up all over the world in the privacy of their homes, offices, boats and even their own little islands.
The obsession with ganja is almost consuming. In a country where there are so many more serious issues like abuse of women, child molestation, incest and petty crime, it doesnt seem to fit. The supply of large scale drugs is something which creates its own industry of zombies and that is worth cracking down on, but in an island where anything you throw on the ground can take root, it doesnt take a major supplier to create a spliff.
It might be worth putting away people who supply drugs for a long time, but unfortunately these people seem to enjoy the best legal support and spend the least time in jail. The lil spliffhead caught in possession is more likely to take jailtime.
One more criminal created.
So what could be done ? Decriminalise it. Give people the right to smoke a limited amount of ganja and if there is possession of any more than sactioned,then the state can get the right to bond them to serve as free working resource for a limited time, like 3 months. Nothing like hard work in the sun at no cost to the state (or a contracted entity) to encourage you to smoke your spliff in private quarters and for your own enjoyment.
As for the gateway argument, it is flimsy at best.
The only gateway from marijuana to cocaine is prison.
